History of Nanotechnology
Richard P. Feyman lecture
the laws of physics do not prevent us from manipulating individual atoms or molecules
1963 Robert A. Freitas 1st company
1979 Thomas Ming Swi Chang Rotor designe
1980 Drexler proposal of a small processor
1st clinical trial
Design of Respiratory Gas carriers
Pressure Vessel
Spherical
diamond
Sensors, detectors, micro processors,
Tiny nickel drums (Rotors)
1000atm – optimal gas molecule packing density
104 bit/sec computer
105 bits of internal memory
Molecular Sorting Rotors
Binding site pockets – rims – 12 arms
Selective binding by coat of antibodies that adsorb
The target molecules
Cam action
Fully reversible – load and unload
2 x 10-21 kg
Sorts molecules of 20 or fewer atoms
106 molecules/ sec
Working of the Artificial Red Blood Cells
Follows threshold values proposed by Drexler
Supply by driving a rotor at the right speed
Supply depending on the need present at that time
The sensors Capacity to detect more than 2 metres at a time
